SPEOIFICATION forming' part of Letters Patent No. 577,408, dated February 23, 1897.

Application filed December 23, 1896. Serial No. 616,817. (No model.)

T all whom, it may ooncrn: i

Be it known that I, PHILIP O. ARNOLD, a citizen of the United States, and a resident of East Hampton, in the county of Middlesex and State of Oonnecticut, have invented certain new and useful Improvement-s in Bells, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a bell with striking mechanism which shall be simple, effective, and compact in construction and by the use of which the bell maybe sounded by a slight pressure upon the operating-lever handle sufficient to cause thev striker-arm to move.

A f urther object is to provide a bell having striking mechanism adapted to strike frequent repeated blows with certainty and clearness.

To this end my invention consists of the several parts and in the combination of such parts, as hereinafter described, and set out in the claims.

Referring to the drawings, Figure 1 is a plan view of the base of the bell, showing the striker mechanism. Fig. 2 is a view in vertical section through the base and the gong, showing the striker mechanism in side elevation. Fig. 3 is a viewin side elevation of the Striker-bar with part cut away to show construction of the Striker. Fig. 4 is a bottom plan view of the Striker-bar. Fig. 5 is a detail view in cross-section of the striker, on enlarged scale, as shown by the dotted outline x of Fig. 4. Fig. 6 is a top View of the carrier-plate. Fig. 7 is a detail edge view. Fig. 8 is a plan View of the Striker-bar. Fig. 9 is an edge View of the same.

In the accompanying drawings my invention is shown embodied in a bell which is particularly adapted fo1` use on a bicycle, although the invention is easily applicable to striking mechanism in bells adapted for other uses.

In the drawings, the letter a denotes the base of the bell, preferably cup-shaped and supporting the Striker mechanism. In the center of the plate a post b serves as a support and means for attachment of the gong c.

The under surface of the base is provided with a clamp d for fastening the bell to the handle-bar or other convenient part of the bicycle.

The lever e is pivoted to the base a, With the end e' projecting and forming a thumbpiece, the inner end of the lever being provided with a curved rack 82, the teeth of which engage a pinion f or arbor which supports the gear-wheel g. This gear-wheel g meshes with a pinion h, which is mounted on the central post b and is free to rotate thereon.

The above-described features of the bell are of ordinary construction in bell mechanism, the special feature of my invention residing in the combination of the striker-arm and the supported strikers.

The striker-arm't` is mounted on the central post and secured to the pinion,with which it revolves. It extends on both sides of the central post, preferably in line of a diameter, and supports a carrier-plate k, which is mounted on the upper surface of the striker-arm and has a limited lengthwise sliding movement thereon. Shoulders or stops limiting the extent of sliding movement of the carrier-plate on the striker-arm are preferably fornied by making an opening Za' through the substance of the carrier-plate and near its outer ends, anarrow portion upturned 'on the end of the striker-arm forming stops on the opposite ends, and these stops extend through the slots 11;/ and coperate with its end walls in limiting the movement of the carrier-plate.

Strikers Z are loosely pivoted on the outer ends of the carrier-plate and onthe pivots Z',

the tapered front end of each striker project-v i in g beyond the outer end of the carrier-plate. In each of the strikers a slot m is formed, and a stop, as z, extends upward into this slot, so as to limit the swinging movement of each striker on its pivot. The slot is of suficient width to permit the lengthwise sliding movement of the carrier-plate on the striker-arm and is of a length to provide for the swinging movement of each striker upon its pivot.

Near each end of the carrier-plate are integral proj ections k2,formed,preferably, of the substance of the plate, and these are turned down and under the striker-arm, where they serve to loosely hold the two parts, the striker-` arm and the carrier-plate, in engagement. The central portion of the carrier-plate is cut away, so as to provide a place throughwhich IOO In prior devices of this class in which the striker is so mounted on the striker-arm as to provide for the indepcndent sliding as Well as rotary swinging movement of the striker the sound of the bell is apt to be sluggish and' not clear. In my improved construction the striking mechanism is Sensitive and the striker hits against the lug with a fiail-like blow, rebounding from the lug freely and -at once swingin g outward by the operation oflthe centrifugalrforce to again'strike the lug in the conltinuedrrotary movement of the 'Strikeribar. (To operatexthebell, pressure is applied :to'itheiouterlendior thumb-piece of the lever, ,'whichcauses' it' to swing on its pivot and move thelrackaround :in contact-with the pinion on :the trainof-gears. This causes the'strikerarmztoibespartially rotated and the `strikers to'hitzagainstthe inner surface of-the bellor the luglthereon. A spring secured at one end to the base and at the other to the leveris'put under tensionby' this movement of the lever, andwhen-.pressure onthe thumb-piece is releasedreverses the :rotary moveinent of the striker-armz and nrings the bell whilethe lever isfswingingback*to-its normal position.

Thelcarrier-plate and the striker-arln are preferably formed of :thin metalstainpedto Shape, bututhe material of ``which these parts are made `or= their. method of 'construction are not material to'the invention.
